Objectives Emerging evidence has shown a role for tumor antigen-specific regulation in cancer. Identifying individuals with pre-existing regulatory responses may be key to understand those who are more likely respond Programmed Death-1 (PD-1) or PD-1 Ligand 1 (PD-L1) checkpoint blockade. We hypothesized that functional assay could identify the of PD-1/PD-L1 interactions on tumor-specific immune cells peripheral blood patients advanced non-small-cell lung cancer (NSCLC). Methods performed...

Individuals harbor preexisting HLA-DR/DQ-restricted responses to collagen type V (ColV) mediated by Th17 cells under Treg control, both specific peptides that bind inherited HLA class II antigens. Yet after transplant, the donor-DR somehow influences graft outcome. We hypothesized that, long a lung or heart allograft, particular HLA-DR of mismatched transplant donor transforms specificity "anti-self" response. This could explain why, over term, certain DRs be more immunogenic than others.We...

Currently, there are no therapies targeting specific pathogenic pathways in myocarditis. IL (interleukin)-1 blockade has shown promise preclinical studies and case reports. We hypothesized that of IL1RAP (IL-1 receptor accessory protein), a shared subunit the IL-1, IL-33, IL-36 receptors, could be more efficient than IL-1 alone.

175 Background: The success of PD-1/PD-L1 inhibition is clearly dependent on optimal patient selection. Developing validated biomarkers that identify patients with an increased probability response to these antibodies remains a challenge. DTH responses are standard method evaluate cellular immune in animal and human immunotherapy trials. trans-vivo delayed-type hypersensitivity (tvDTH) methodology, using the SCID mouse footpad swelling PBMC (peripheral blood mononuclear cells) + antigen...

Abstract IL-1, IL-33 and IL-36 have complementary pro-inflammatory roles during the immune response promoting autoimmune inflammatory diseases, such as myocarditis. Therapeutic blockers targeting IL-1 pathway previously been developed. However, we hypothesized that blockade of shared co-receptor these three pathways, receptor accessory protein (IL1RAP), would exhibit a more potent broader anti-inflammatory profile. To investigate this hypothesis, induced coxsackievirus B3 (CVB3)-mediated or...

In Spanish colonial California, the folk-hero "Zorro" left his mark on by a sword- slashed "Z".In transplant recipients, rare Tregs also leave their conventional T & B LC targets. This is caused Ag-specific CD4 that release IL35-coated exosomes, “cross-dressing” (xD) targets with IL35. Hypothesis We wished to test 3 hypotheses related this finding: 1) just as MHC+ exosome “passenger” DC greatly amplifies alloactivation xD of host DC, IL35 suppression passenger amplified cells; 2) monitoring...

IL-1, IL-33 and IL-36 have complementary, pro-inflammatory roles during the immune response that promote autoimmune diseases, particularly myocarditis. While antibodies neutralize circulating cytokines exist, we hypothesized blockade of their shared co-receptor, IL-1 receptor accessory protein (IL1RAP), would exhibit a more potent broader anti-inflammatory profile. The CAN10 antibody blocks IL1RAP is currently under development for treating severe inflammatory diseases. To investigate if an...
